ABSTRACT:
An image-taking apparatus is disclosed, which is capable of reducing the influence of the one-side blur by the automatic focusing function. The image-taking apparatus comprises a focus detector, which detects the focus state of the plurality of focus detection areas, and a selector, which selects a focus target area from a plurality of focus detection area based on the detection result of the focus detector. In a case where a first object distance to a first object is longer than a first predetermined distance, and a second object distance to a second object, which exists on an outer side of the first object in the image-taking screen, is shorter than the first object distance by a second predetermined distance or more, the selector selects the focus detection area corresponding to the second object as the focus target area.
